Globally biodiversity is on a decline with time. Hence, the regular documentation of biodiversity of any region is the most important asset for long-term survival of species in that region. Grasslands are considered as a highly productive ecosystem. They play a crucial role in providing suitable habitats for fauna and ideal foraging grounds for animals such as birds, reptiles and mammals. Over 50% of grassland habitats have been lost and degraded in the past two decades due to human interventions especially clearing it for agriculture activities. Thus, habitat destruction/degradation is the major threat to species adapted to grasslands. During the present investigation, the presence of birds, mammals, and reptiles was recorded by using direct observation is Sorsan Grassland of Baran district, Rajasthan (India).
